Tonix Pharmaceuticals Completes Convertible Note Offering

Capital From Board of Directors and Current Investors to Fund Further Development of TNX-102 SL to Treat Fibromyalgia and Post-Traumatic Stress Disorder

NEW YORK, NY--(Marketwire - Nov 14, 2012) - Tonix Pharmaceuticals Holding Corp. (OTCQB: TNXP) ("TONIX" or the "Company"), a specialty pharmaceutical company developing novel treatments for challenging disorders of the central nervous system, including fibromyalgia ("FM") and post-traumatic stress disorder ("PTSD"), today reported that it has raised $710,000 in a convertible note offering. The notes bear interest at 8% and may convert into a future private placement at a 25% discount unless redeemed. The notes have a one year term and may be converted into shares of the Company's common stock at a conversion price of $1.00 per share, which reflects an approximate 100% premium to the market price on the date of closing. The funds will be used to further the development of the Company's TNX-102 sublingual tablet ("TNX-102 SL"), a proprietary formulation of cyclobenzaprine ("CBP") for bedtime use.

"We are pleased our Board of Directors has led this financing, which will fund the further the development of TNX-102 SL to help people afflicted with FM obtain pain relief by improving sleep quality," said Seth Lederman, M.D., Chief Executive Officer of TONIX. "We have developed the new sublingual tablet specifically as a bedtime therapy for fibromyalgia. This financing keeps us on track to begin enrolling patients into the first of two pivotal efficacy studies of TNX-102 SL in FM in the first quarter of 2013."

Dr. Lederman continued, "We believe the improved pharmacokinetic ("PK") profile of TNX-102 SL can potentially provide several clinically meaningful advantages over marketed oral formulations of CBP including possibly faster onset of action, which is desirable for a bedtime medication. We also believe that our targeted dose and dosing regimen will be associated with lower rates of side effects such as next-day somnolence. We look forward to executing on our clinical study plan for what we believe will be a much-needed treatment option for patients with FM. We expect the same TNX-102 SL formulation to enter proof-of-concept studies for PTSD next year."

About Fibromyalgia

Fibromyalgia is a common and complex central nervous system condition characterized by chronic diffuse musculoskeletal pain, increased pain sensitivity at multiple tender points, fatigue, abnormal pain processing and disturbed sleep, and often features psychological stress. Despite the fact that most FM patients suffer from poor sleep, there are no medications indicated for FM that work by improving sleep quality. It is estimated that five million people are suffering from FM in the U.S.

About PTSD

PTSD is an anxiety disorder that can develop from seeing or experiencing a terrifying event or ordeal in which there was the threat or actual occurrence of grave physical harm. PTSD was once associated primarily with war veterans, but civilian PTSD can be triggered by serious accidents, natural or human-caused disasters, exposure to terrorist attacks, violent personal assaults or sexual abuse, or even sudden and major emotional losses. People with PTSD experience persistent symptoms that include strong and unwanted memories of the event, bad dreams, emotional numbness, intense guilt or worry, angry outbursts, feelings of anxiety, and avoiding thoughts and situations that are reminders of the trauma. The National Institute of Mental Health estimates that PTSD affects about 7.7 million American adults at some point during their lifetime.

About TONIX

TONIX is developing innovative prescription medications for challenging disorders of the central nervous system. The Company targets conditions characterized by significant unmet medical need, inadequate existing treatment options, and high dissatisfaction among both patients and physicians. TONIX's core technology improves the quality of sleep in patients with chronic pain syndromes, which is believed to translate into reductions in daytime pain. The Company's lead product candidate, TNX-102 SL, is a novel under-the-tongue tablet formulation of CBP, the active ingredient in two U.S. Food and Drug Administration ("FDA")-approved muscle relaxants, and is expected to enter a Phase 3 program in FM in early 2013. TNX-102 SL is an Investigational New Drug. An Investigational New Drug Application ("IND") has been filed with the U.S. FDA for TNX-102 for FM. TONIX is also exploring the utility of TNX-102 SL in a new bedtime treatment paradigm for PTSD. The Company has also held a pre-IND meeting with FDA to discuss PTSD and is planning to file a second IND in early 2013.

In a randomized, double-blind, placebo-controlled, eight-week Phase 2 trial, TONIX demonstrated that low-dose CBP given at bedtime resulted in a significant decrease in next-day pain and other core FM symptoms, as well as in a significant improvement in sleep quality. Legacy CBP products are widely used by FM patients, but are neither designed nor approved for this indication. TNX-102 SL has demonstrated faster systemic absorption relative to administration of the 5 mg CBP tablet in a Phase 1 comparative PK and safety study in healthy volunteers. In that study, TNX-102 SL 2.4 and 4.8 mg was generally well tolerated. There were no unexpected adverse events, with the exception of a mild, temporary numbness at the tongue experienced by less than one-third of the subjects that received TNX-102 SL tablets.
